You cannot have a dictionary (a keyed list) with the same key multiple
times like above. keys MUST be unique!

The value at each key could be a list as in:

{ a: ['trev', 'lee'], b: ['gold', 'gold'] }

A python script could create a dictionary of lists like so:

PARAMETERS: records

r = {}
for rec in records:
   if r.has_key(rec.key):
       r[rec.key].append(rec.value)
   else:
       r[rec.key] = [rec.value]
return r
